Surveys for invertebrates are required for a wide range of developments, and to guide the management of sensitive wildlife sites. Many species of invertebrates are under-recorded nevertheless they are still crucial to national biodiversity. Many invertebrate species/groups have undergone significant declines, and this is recognised through the statutory/non-statutory status afforded to certain species.

Invertebrate survey is relevant in relation to the Wildlife and Countryside Act, Section 74 (CROW Act) and UK BAP species.

Pennine have undertaken aquatic invertebrate surveys in relation to major pipeline projects and are currently monitoring butterfly/dragonfly populations as part of a nature reserve management plan.
